Notes:
1 Maximum input current at low input voltage range should measured at 90VAC, at max load.
2 Maximum input current at high input voltage range should be measured at 180VAC, at max load.
3 Do not use this requirement for determining agency input current markings.
2.1.4.1 AC Inlet Connector
The AC input connector is an IEC 320 C-14 power inlet. This inlet is rated for 10A / 250VAC.
2.1.4.2 Efficiency
The power supply has a recommended efficiency of 68% at maximum load and over the
specified AC voltage.
2.1.4.3 AC Line Dropout / Holdup
An AC line dropout is defined to be when the AC input drops to 0VAC at any phase of the AC
line for any length of time. During an AC dropout of one cycle or less the power supply meets
dynamic voltage regulation requirements over the rated load. An AC line dropout of one cycle or
less (20ms min) does not cause any tripping of control signals or protection circuits. If the AC
dropout lasts longer than one cycle, the power recovers and meets all turn-on requirements.
The power supply meets the AC dropout requirement over rated AC voltages, frequencies, and
output loading conditions. Any dropout of the AC line does not cause damage to the power
supply.
2.1.4.3.1 AC Line 5VSB Holdup
The 5VSB output voltage stays in regulation under its full load (static or dynamic) during an AC
dropout of 70ms min (=5VSB holdup time) whether the power supply is in the ON or OFF state
(PSON asserted or de-asserted).
2.1.4.4 AC Line Fuse
The power supply has a single line fuse on the Line (Hot) wire of the AC input. The line fusing is
acceptable for all safety agency requirements. The input fuse is a slow blow type. AC inrush
current does not cause the AC line fuse to blow under any conditions. All protection circuits in
the power supply do not cause the AC fuse to blow unless a component in the power supply
failed. This includes DC output load short conditions.
